GR'ILLE.

Application filed Augnst21; 1925. Serial No'. 51,619J

This invention" relates to grilles and iS particularly related to the means for fasten i'ng the edge to the body of grilles such'as ar'e'used for :the protection of doors and windows and as cities and bank partitions and: for sin'iilar uses.

In the manufactureot grilles,at the prescnttiniey the means torfastening the-body totlie edges thereof-are usually at fixed places. This construction makes necessary accurate fitting of the fastening means and causes di-iii'culty in obtaining registrationof the-securingmeans in the edge with the coacting portion in the body. Further, the fixed relation of the edge-relative to the body, results in difficulty in tittin the grilles to places where they are'being installed.

Tlieprim'ary object of the present=inven tion 'is'theprovision or an improved window door and partition gri'llewhich will not emliio'dy structure open to theabove noted objections:

Otherobfects of my invention are to produce a grillc -fordoors, windows, partitions and: like purposes which, (1') will have a series ot attaching means to connect the body to theed'ge and which need not necessarily be exactly the same distance apart, (2) will be so constructed that the securing means 39 may be placed in the edge'and afterward attached'to the body or*-(3) may be first attached to the bodv and then the edge applied,..(4i). will be capable of easy repair in case of'da'mage and without the need of an expert w0rkman,(5)will be capable of assem bly by unskilled workmen, (6) will be cheap of manufacture (7) strong of construction and (8) will yield between the body and edge portions when pressure is brought against the same.

Other and further objects will be apparent to those skilled in the art from a reading of the complete specification and claims.

Referring to the drawing wherein I have illustrated an embodiment of my invention,

Fig. 1 is front view of a fragmental por tion of a grille and having its edge made according to my invention.

7 Fig. 2 is a top plan view. 0 Fig. 3 is sectional view on the line 3-3 of Fig. 1.

Fig. 4 is a cross sectional view on the line 14 of Fig. 1.

Fig. 5 is a top plan view of the connector. Fig. {3 is enlarged cross sectionalv view on the line 66 of Fig.2, the edge member being omitted.

Like reference characters refer to the same or similar parts throughout the several views. I V

The numeral 10 designates the horizontal bars and 11 the Vertical bars of the grille 'llustrated-in the drawing ancl..-embodying my invention. At the end: of thehorizontal bar, as illustrated, I have shownaspi-ralornamental end 12, the outer coil:ot-which is nearly tan-gentto the edge member 13.

The edge member 13 is intheform of hollow cylindrical member such asa pipe and havinga slot 14; throughout'its length.

Thisslot 1a is provided to cooperate with a connecting means slidable therein andconv nected to the'body' of the grille.

The connectingmeans is provided with/a portion within the edge -membcr' which, when in position,- cannot be removed through the slot. This portion is ShOWIl' as'a cylindrical portion 15 as clearly shown in Figlflfl The ends oi. the cylindrical portions lie together at 16' and extend through the slot 145.: Afterpassing through the 'slot 14,-nthe: two ends of the connecting means separate and extend around theouter loops 120i thespirals at the ends of the horizontal.membersll. -At4 ensurrounding the loops 12, the ends of the connecting. means overlap as -illu-strat+ ed at 17. w

In ::assembl1ng-*-the* parts, eitherv of two differentmethodsf may bet-used. Thewbody of the grille, having been completed, the connecting members may be all placed in the slot 14, their ends not being closed to lapping position as at 17, but open to receive the outer coil of the spiral. The connecting members are moved in the slot until opposite the coil to which it is to be attached. After the coil has been placed in the con necting means, the ends of the latter are bent over as illustrated in the drawing.

If desired, the connecting means may be first applied to the outer coils 12 after which the edge member is slid over the cylindrical portions 15.

My improved connecting means makes unnecessary the registration of holes in the edge member with similar holes in the spiral member, for riveting as in some types oi grilles. In addition, the assembly operations are simple, and may be quickly and easily performed by inexpert workmen.

til

Also, the grille may be easily repaired in case of damage and the parts will yield by sliding in the slot and by the spiral portion sliding in the connector when pressure is brought to bear on the grille body.

While I have illustrated and described an embodiment of my invention in detail, I desire to have it understood that I do not limit myself to the exact showing and that modifications and changes may be made without departing from the spirit of my invention and within the scope of the appended claims.

Having described my invention, what I claim is 1. A grille having a body portion and an edge member, a plurality of means for yieldingly connecting the body portion and edge member together whereby the body member may yield relative to the edge member in a direction parallel to the edge member and also yield resiliently toward and from. the edge member.

2. A grille having a body portion and an edge member, the boc y portion being provided with resilient members adjacentbut outside the edge member, and separate means for yieldingly connecting the edge member to the resilient members.

3. A grille having a body portion and an edge member, the body portion being provided with resilient members adjacent the edge member, the edge member being provided with a guide means along its length and separate means for connecting the guide means to each of the resilient members.

A. A grille having a body portion and a hollow edge member, the body portion being provided with a resilient member adjacent but outside the edge member, the edge member being provided with a groove along its length and separate means slidable in the groove and connected to the resilient memher to hold the edge member to the body portion.

5. A grille having a body portion and a hollow edge member, the edge member being provided with a slot and means slidable in the slot and yieldably connected with the body member to connect the latter to the edge member but outside the slot thereof.

6. A grille having a body portion comprising a plurality of spring members adjacent its edge, a hollow edge member provided with a longitudinal slot, means for connecting the spring members to but outside the edge members, each comprising a portion within the hollow edge member having a greater width than the slot, a portion extending through the slot and a portion surrounding a portion of the spring member.

7. A grille having a body portion comprising a plurality of spring members adjacent its edge, a hollow edge member pro vided with a longitudinal slot, means for connecting the spring members to the edge member, each comprising a sheet metal strip having. a portion within the edge member bent in the form of a cylinder, portions extending through the slot'and bent around aportion of the spring members.

8. A grille having a body portion, a hollow edge member provided with a longitudinal slot, means for connecting the body portion to but outside the edge member, each comprising a sheet metal strip having a portion within the edge member bent to have a greater width than the slot in the edge member, a portion extending through the slot and a portion surrounding a part of the 7 body portion of the grille.

In testimony whereof I hereunto affix my signature.
